Those same twin studies "prove" a genetic link to homosexuality. I question the twin studies that indicate such things, because the famous ones are based on severely flawed models.

So because you don't like the results of one genetic study you will throw out the results of them all? Were you an OJ Simpson juror by chance?

MANY different studies have studied identical twins (monozygotic) raised apart and found a 0.70 correlation for intelligence. This is enormous.

The Stanford-Binet test does presuppose some cultural knowledge. Once you correct for socioeconomic factors, that 15-point gap vanishes to within the MOE.

Look up the Minnesota transracial adoption study. They found that the average IQ of black babies adopted by white couples was around 85, the average IQ of half black babies adopted by white couples was 95, and the average IQ of white babies adopted by white couples was 105.

No, I'm questioning the whole basis of many of these twin studies, because some of the more famous ones that get cited were "pre-loaded" to get certain results.

Great, if true.

Question: did they correct for the nurture end of things?

I've bumped into too many identical twins with very different overall temperments (intelligence, WHAT they're good at, personality, et cetera) to buy in that intelligence is that strongly determined by genetics. I have one rather smart sister, and two fair-to-middlin' brothers--and in mathematics, I'm the best of breed in my family. My sister and brothers are very coordinated; I'm something of a klutz. We're all over whatever charts you want to look at.
